Both of these coolers from Gigabyte performed better than I thought they would. To be honest, I didn't expect too much from a Gigabyte cooler as they haven't been in the heatsink business as long as other companies. The reality is that their coolers are decent choices if you are looking for a flashy and/or quiet alternative to stock cooling on your computer. They don't keep up with the biggest and the best from Zalman, but they do compete very well with the CNPS8000 and will compare nicely with many other coolers on the market.
